Specification of Letters Patent.

Patented May 6, 1919.

Application filed January 14, 1 919. Serial No. 271,127.

To all whom it may concern:

Be it known that I, EDoUARn E. NININ, a citizen of France, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hair-Cutters, of which the following is a specification.

This invention relates to cutlery, and more especially to rotating knives; and the object of the same is to produce a hand implement for cutting human hair.

One object of the invention is to provide means for driving the cutting reel by moving the implement over the head. a

Another object is to adapt thedevice to the cutting of hair at therequired length by setting a movable blade.

Another object is to provide this device with a comb, and means for keeping it in alinement with said movable blade.

Another object is to provide means for round heads 2ofthe frame or casing and to be protected to an ex ent by the end Walls readily replacing the blades in the reel when they become dull. j

Other objects will be disclosed in the following specification and claims. Referring Figure 1 is a side elevation of this device partly broken away,

Fig. 2 is a section on the line 2-2 of Fig. 1, and Fig. 3 is a section at right angles.

to the sectional line of Fig. 2.

The frame 1 is shaped in sectionas seen in Flg. 2, each pendant arm termlnating 1n a head2 which is practicaIlV IOUIid and each arm above its head also having anupright slot 3, while the arch 4 connectingthearms may have a perforation 5 at its center; The edges of the arms may be connected by walls 6 to givestrength to the partsand to produce a substantially rectangular "handle at the upper end of the frame, but these walls should terminate short of the working part of the device, and certainly they should leave the front of the frame open so access to the reel, and the bottom of the frame open so that the hair can enter. This last opening is indicated at 7, and near it a cross bar 8 connects the heads if thought necessary.

Projecting outward from the center of each head is a stub shaft 10whose outer end head of the person whose hair is being cut.

arms 24- of the pair.

This wheel carries a ringl l of internal gear teeth from which power is communicated shaft 16 which carries gears 17 meshing with pinions 18 fast on a counter shaft 19 located above said shaft 16 as perhaps best seen in Fig. 2. The counter shaft 19 in turn carries gears 20 meshing with pinions 21 on the hub 22 of the reel which is mounted on the shaft 16. The latter may therefore be called the reel shaft, although it will be understood that the reel is rotated thereon much more rapidly than does the shaft itself. Asseen in Fig. 3,the reel shaft is disposed below the axis of the stub shafts 10, while the counter shaft 19 is above the same. All the gears mentioned are of a size to be well contained within the peripheries of the 6 aswell asthe side wall or arms of the frame itself. In a simpler and cheaper type of the machine it might be possible to drive the reel by a train of gearing connected with one main wheel, and omit it at the other side; but I prefer to drive it from both main wheels-as shown and described. However,

i I do not wish to limit myself in this respect, nor as to the details of the train itself. The

screw 27 and having arms lying against said blades,] and a rather heavy nut 28 threaded onto the screw 27 against the body of the washer so as to hold the same down upon the hub and at the same time cause its arms to clamp thetwo blades 25 against the two The other pair of blades are held by another washer at the opposite sideof the hub in the same way. However, itis obvious that there might be a greater number of reel arms and a corresponding alteration inthe construction of the washers, or in fact the details of the reel itself might be varied considerably without departing from the spirit of the inventlon. As thus described, the nuts are accessible through the large front opening 29 in the.

frame or casing between the two heads, and when the nut has been removed and the washer removed or loosened, the blades can be withdrawn, replaced, adjusted or handled as may be necessary. I would make the nuts 28 rather heavy to give momentum to the reel when .it isrotated by the train of gears described above, but even this suggestion may be disregarded if thought necessary.

- the .ends .of this blade and carry outstanding pins 3 1 which pass through slots 33 in lthe heads 2 .of the casing, such slots being concentric with the aXis-ofthe reel itself. In addition, the ends of the blade travel on v ribs v33, and the blade itself is curved transversely and slightly so as to fit accurately against these ribs as it is adjusted toward and from theiopening 7 Outside each head of the frame is a rock arm 36 pivotally mounted onthe stub shaft 10 and having a slot 34 in its lower end to loosely receive the {pin .31 where the same projects beyond the head 2, and pivoted to the upper end of said arm above the stub shaft is a link 37 rising through the hanger 11 if the latter be employed. The npper ends of the links are connected :by means of a rod :38 slidably mounted in the slots 13 above referred to,

and said rods may-have knobs or buttons 39 on its extremities, or a single knob or handle 39 projecting through the opening 5 in the arch 4 of the frame, or both as shown in Fig. 2,, the obvious purpose being to give the operator means for adjusting :the rod 38 vertically within the slots 3. Such adjustment swings the arms 36 whose slots 34 by engaging the pins 31 adjust the cutting edge of the blade 35 toward :or from the opening 7.

' The comb 45 has .teeth 43 at its front edge projecting toward the opening'Z, while arms 405'rise from the ends and have outstanding pins 41 also mounted in the slot 34 of the rocker arms 36. The body of the comb may be curved slightly as shown, and it is guided in a cut-out 42 around the .ed-geiof the heads 2, .as best seen in Fig. 3. Therefore the comb moves when itis adjusted, around the center ,of the stub shafts 10 which of course 1 is the center of the round heads: Adjustment is effected by the same means that adjusts the blade .35., and at the same time, and

therefore the comb and blade will move together. It is of course necessary that the blade should be adjusted accurately around the center of the reel, because its cutting edge coacts with the lower edges of the blades 25 on said reel. But it will be seen that, as the blade is adjusted to the right in Fig. 3, the blade in being adjusted in the same direction recedes from the comb inward, whereas in the position of parts illustrated these elements are practically in contact. The result will be that the hair will be cut longer when adjustment is effected, whereas with the parts standing in contact as shown, the hair would be out quite short.

The operation of the device will be readily understood. Movement of the main wheels over the head of the person whose hair is being cut rotates the reel at a relatively high rate of speed, its blades 25 moving toward the relatively fixed blade 35 and their edges coacting with the cutting edge thereof in the usual manner. Setting the parts as described will regulate the length of the haircut, and such setting is under the immediate control of the operator. This is because the hair must be cut short at certain places on the head and longer elsewhere. While I have described this device as useful for cut ting hair .on the human head, it is quite obvious that it could be employed in other ways, and I do not wish to be limited in that respect.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, .et cetera, as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is 1.
